A Blockchain-based Access Control Scheme

Access control plays an important role in protecting data privacy. However, traditional access models such as RBAC, ABAC and UCON need to be built based on a central trusted server. Once the server is controlled by adversary, it will pose serious threat security. Therefore, this article proposes blockchain-based scheme, which uses blockchain replace smart contracts complete access. The proposed scheme solves centralization problem of model. Furthermore, has been tested representative equipment, experimental results show that efficient feasible.
